I'm 5'2", 125lbs- I prefer the carlisle guide stick for high water specifically because of the weight it helps me throw around. At low water, a custy stick is fine.
I second that you don't need to buy a guide stick in your rookie year (unless you have money to throw away). If you get the bug, you aren't going to stay in that concrete playpark for long. Pretty soon you'll be running shit just a tad over your skill level and you will lose that fancy new guide stick.
